Ok, I Own a 2007 ram 3500 single cab with 86k miles. I get "exhaust filter full" and "power reduced" message. It appears everytime I turn on my truck and them I scroll down to see the MPG and the message will never come up again until I will turn off and then on the truck. I just bought this truck, I had the old 5.9 liters so Im new with this new technology. Any suggestions or recomendation?? Is this under factory warranty or just some stupid message?? I can I solve this problem for good?? :confused013: I read and Im suppose to drive it on the highway for 45 min. but I bought the truck in Texas and drove it to Floridal; 16 hour drive and the message for the exhaust filter full stills appears. The truck runs and drive nice. The power have no reduced or anything yet. Is this something I should take it to de dealership and have them solve the issue???????
